Abstract
Description
Die Erfindung betrifft einen Fluidfilter für einen Kraftfahrzeugmotor.The The invention relates to a fluid filter for a motor vehicle engine.
Sie ist insbesondere auf Fluidfilter gerichtet, die
- – ein Gehäuse, das einen lösbaren Deckel, einen Behälter, der einen Boden besitzt, ab welchem sich eine im Wesentlichen ringförmige Wandung axial erstreckt, die mit dem Deckel verschlossen wird, und einerseits einen Fluideinlass und -auslass, wobei einer von Fluideinlass und -auslass aus einem Fluidrohr besteht, das sich ab dem Boden des Behälters axial erstreckt, und andererseits einen Ablasskanal, der in einem Teil des Bodens des Behälters und zwischen Fluideinlass und -auslass mündet, umfasst,
- – eine Filterpatrone, die einen ringförmigen filternden Teil umfasst, der einen leeren Innenraum begrenzt, in welchem das Fluidrohr angeordnet ist, wobei sich der filternde Teil zwischen einem in der Nähe des Deckels befindlichen ersten Ende und einem in der Nähe des Bodens befindlichen zweiten Ende axial erstreckt und erstes und zweites Ende des filternden Teils an einem ersten bzw. zweiten ringförmigen, im Wesentlichen starren Flansch dicht befestigt sind, und
- – Dichtungsmittel, die am zweiten Flansch angeordnet sind, um, wenn sich die Patrone an ihrer Stelle im Gehäuse befindet, Dichtheit zwischen Fluideinlass und Ablasskanal und zwischen Fluidauslass und Ablasskanal sicherzustellen, wobei die Dichtungsmittel ein ringförmiges axiales Dichtungselement, das zwischen dem zweiten Flansch und dem Fluidrohr axiale Dichtheit sicherstellt, und ein radiales Dichtungselement umfassen,
- A housing having a releasable lid, a container having a bottom from which axially extends a substantially annular wall which is closed with the lid, and on the one hand a fluid inlet and outlet, one of fluid inlet and outlet consists of a fluid tube which extends axially from the bottom of the container, and on the other hand comprises a discharge channel opening in a part of the bottom of the container and between the fluid inlet and outlet,
- A filter cartridge comprising an annular filtering member defining an empty interior in which the fluid tube is disposed, the filtering member axially between a first end located near the lid and a second end located near the bottom and first and second ends of the filtering member are tightly secured to first and second annular, substantially rigid flanges, respectively, and
- Sealing means disposed on the second flange for securing, when the cartridge is in place in the housing, sealing between the fluid inlet and the outlet channel and between the fluid outlet and outlet channel, the sealing means comprising an annular axial sealing element disposed between the second flange and the outlet Fluid tube ensures axial tightness, and include a radial sealing element,
Ein
Filter dieses Typs ist in der europäischen Patentanmeldung
Weiterhin bildet dieses röhrenförmige Element einen Auflagepunkt, der in Bezug auf die Achse der Patrone exzentrisch ist und während des Anbringens oder des normalen Betriebs der Filterpatrone auf dem zweiten Flansch Biegespannungen verursacht. Diese Biegespannungen sind jedoch für diesen Typ einer Filterpatrone schädlich. Sie verursachen insbesondere ein Verkippen des zweiten Flansches und somit einen Dichtheitsverlust zwischen Fluideinlass und Ablasskanal. Ein solcher Dichtheitsverlust ist bei Normalbetrieb des Filters selbstverständlich inakzeptabel.Farther forms this tubular element a support point that is eccentric with respect to the axis of the cartridge is and while mounting or normal operation of the filter cartridge causes the second flange bending stresses. These bending stresses are however for this type of filter cartridge is harmful. They cause in particular a tilting of the second flange and thus a leakage between the fluid inlet and the outlet channel. Such a leakage is of course unacceptable during normal operation of the filter.
Deshalb liegt der Erfindung die Aufgabe zugrunde, die vom zuvor beschriebenen Stand der Technik verursachten technische Probleme zu lösen, wobei das Ausüben von Spannungen auf die Filterpatrone vermieden wird, welche diese verformen können, wenn sie sich im Gehäuse an ihrer Stelle befindet.Therefore The invention is based on the object, from the previously described State of the art caused technical problems to be solved, wherein the exercise of stresses on the filter cartridge is avoided, which these can deform, when they are in the case is in its place.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass jener Teil des Bodens ein ringförmiger Teil des Bodens des Behälters ist, der einen Innenumfang, der von einem Teil der Wand des Fluidrohrs definiert wird, und eine flache Oberseite besitzt, auf welcher das radiale Dichtungselement aufliegend vom zweiten Flansch der Patrone gehalten wird, um radiale Dichtheit zwischen dem zweiten Flansch und dem Teil des Bodens sicherzustellen, wenn sich die Patrone an ihrer Stelle im Gehäuse befindet.These Task is inventively characterized solved, that part of the soil forms an annular part of the bottom of the soil container is that of an inner circumference of a part of the wall of the fluid pipe is defined, and has a flat top on which the radial sealing element resting on the second flange of the cartridge is held to radial tightness between the second flange and to ensure the part of the bottom when the cartridge is attached their place in the housing located.
In den erfindungsgemäß bevorzugten Ausführungsformen wird/werden außerdem die eine und/oder die andere der folgenden Anordnungen verwendet:
- – der zweite ringförmige Flansch ist mit einem radialen Innenrand versehen, der sich ab dem filternden Teil erstreckt und ein Ende umfasst, das in Richtung des leeren Innenraums der Patrone axial umgebogen ist, und das axiale Dichtungselement der Dich tungsmittel ist zwischen dem umgebogenen Ende des zweiten Flansches und dem Fluidrohr angeordnet,
- – das axiale Dichtungselement besitzt einen radial hochstehenden Rand, der an das umgebogene Ende des zweiten Flansches anschlägt,
- – das axiale Dichtungselement und das radiale Dichtungselement sind aus einem Stück ausgebildet und das radiale Dichtungselement erstreckt sich ab dem axialen Dichtungselement radial nach außen,
- – die Länge des Fluidrohrs ist mindestens gleich der Hälfte der Länge der Filterpatrone,
- – der Fluidauslass wird vom Fluidrohr gebildet und
- – der ringförmige Teil des Bodens des Behälters steht über und besitzt einen Außenumfang, der mit einem Teil der ringförmigen Wandung des Behälters eine ringförmige Auskehlung bildet, in welche der Fluideinlass mündet.
- - The second annular flange is provided with a radial inner edge which extends from the filtering part and comprises an end which is axially bent in the direction of the empty interior of the cartridge, and the axial sealing element of the sealing means is between the bent end of the second Flange and the fluid pipe arranged
- The axial sealing element has a radially upstanding edge which abuts against the bent end of the second flange,
- The axial sealing element and the radial sealing element are formed in one piece and the radial sealing element extends radially outward from the axial sealing element,
- The length of the fluid tube is at least equal to half the length of the filter cartridge,
- - The fluid outlet is formed by the fluid pipe and
- - The annular part of the bottom of the container projects beyond and has an outer periphery which forms with a part of the annular wall of the container an annular groove, into which the fluid inlet opens.
